public class CtaSimToS_provider

extends org.omg.CosEventComm._PushSupplierImplBase

Class CtaToS_provider sends the necessary responses to requests for changing the usage level of a given station. The format of the responses is:

'CTRL_RESULT:SSSSS:ID:AGENT:COMMAND:ARGS'

where SSSSS is the station name, ID is the id of the cta message manager in the NSI, AGENT is the name of the replying control agent, and COMMAND:ARGS is the result command and its return arguments. ARGS is optional.

There are currently four possible CTRL_RESULT messages:

1. ACK -- This command is returned by the CTA controling the station to acknowledge the receit of a CTRL_MSG request. Its argument syntax is:

ACK:USAGE:TIMEOUT

where USAGE is the desired usage echoed back and TIMEOUT is the maximum number of seconds the control operation will requre to complete.

2. DONE -- The DONE result command is returned by the CTA once the usage level change operation is complete. This result command has no argments.

3. FAILURE -- The FAILURE result command is returned by the CTA if the usage level change does not happen successfully. That is, the script or program being executed exits abnormally (non-zero exit status).

4. TIMEOUT -- The TIMEOUT result command is returned by the CTA if the script or program being executed has not returned after the advertised timeout indicating a problem or a poorly defined timeout setting.
